Exhibits antimicrobial activity against Gram-negative bacteria and Gram-positive bacteria, with highest activity against Gram-negative bacteria (PubMed:10837369, PubMed:9202117). Antimicrobial activity against P.aruginosa seems to be salt-sensitive and is reduced with high salt concentrations greater than 25 mM (PubMed:10837369). Also exhibits antimicrobial activity against the yeast C.albicans (PubMed:10837369, PubMed:30050988, PubMed:9202117). Permeabilizes C.albicans cell membranes via targeting plasma membrane lipid phosphatidylinositol 4,5-bisphosphate (PIP2), thereby leading to cell fragmentation and cell death (PubMed:30050988). Acts as a ligand for C-C chemokine receptor CCR6 (PubMed:10521347, PubMed:20068036). Binds to CCR6 and induces chemotactic activity of CCR6-expressing cells, such as immature dendritic cells and memory T cells (PubMed:10521347, PubMed:20068036).

Beta 2 defensin also known as BD-2 or beta-defensin 2 is a small antimicrobial peptide with a molecular mass of about 4.6 kDa. It plays an important role in the innate immune response by disrupting microbial membranes. BD-2 is expressed in epithelial cells making it important for creating a protective barrier in the skin respiratory tract and urogenital tract. This peptide acts directly against bacteria fungi and some viruses helping to maintain microbial homeostasis in these areas.
Beta 2 defensin serves as a critical component of host defense mechanisms. It not only shows antimicrobial properties but also influences inflammatory processes. BD-2 interacts with immune cells recruiting and activating them for enhanced defense response. Presently there is no evidence of beta 2 defensin being part of a larger protein complex focusing its function on immediate immune response and cellular signaling in areas it is expressed.
Beta 2 defensin engages in critical pathways of immune protection. It is part of the toll-like receptor signaling pathway and engages the NF-kB pathway. These pathways are essential for activating immune responses when pathogens are recognized. Additionally beta 2 defensin interacts with other defensins and related antimicrobial peptides to mount an effective immune response coordinating with various cytokines and chemokines to balance protective actions.
Beta 2 defensin has connections to inflammatory and autoimmune conditions. It has a potential link to psoriasis where its expression levels are increased serving both protective and inflammatory roles. BD-2 is also investigated in cystic fibrosis where its impaired function can contribute to chronic lung infections. In these conditions the altered balance of BD-2 associates it with proteins involved in immune dysregulation contributing to the pathophysiology of these disorders.
